KiRa [710]

Answer:

x = 33

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

x+114+33 = 180

Combine like terms

x+147 = 180

Subtract 147 from each side

x+147-157 = 180-147

x = 33

An air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute. Select all
Radda [10]

Answer:

The correct options are 3, 4 and 5.

Step-by-step explanation:

It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.

It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).

The ball falls at a rate of 50 ft per minute. So, the rate of change is

m=-50

The height of balloon is defined as

h(x)=-50x+1000                      [\because y=mx+b]

Where, x is time in minutes.

The balloon will reach the ground when h(x)=0

0=-50x+1000

50x=1000

x=20

Therefore the options 3, 4 and 5 are correct.

A national survey interviewed 3800 people ages 18 and older nationwide by telephone. One question asked was the amount of gasoli
NeTakaya

Answer:

For this case a parameter represent the population data and for this case the parameter would be the true mean \mu who represent the amount of gasoline they used in the previous week

\bar X= \frac{\sum_{i=1}^n X_i}{3800} =11.75

And the sample mean is an unbiased estimator of the true mean.

Step-by-step explanation:

For this case a parameter represent the population data and for this case the parameter would be the true mean \mu who represent the amount of gasoline they used in the previous week

And in order to estimate the parameter of interest we use a survey of n =3800 and the sample mean who represent an statistic is given by:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

And we got:

\bar X= \frac{\sum_{i=1}^n X_i}{3800} =11.75

And the sample mean is an unbiased estimator of the true mean.
